Urgent help required

[Garetht]

My MK1 leon TDI has developed a knocking noise when turning left, you can here it at 50mph plus but below 50mph nearer 30-40mph it is really loud. The faster you drive the faster the knock and vice versa!!!

Anyone got any ideas ?

Need any pointers pretty quick as I have a 400 mile round trip on Wednesday for a funeral and need to get this fixed.


Cheers G

Has your car been lowered?

 

[Garetht]

No, it is totally standard.

Also forgot to mention that there is no vibration.

Check your wheel nuts aren't loose! I had a similar thing a while back. Turned out someone tried to steal my wheels but couldn't get the locking nuts off so they were just left loose. Jacked it up and the wheel almost fell off. I was driving on the motorway when I heard a knocking noise. Very lucky.

Wheelbearing

wheel bearing on the way out??

 

[Black TDI Turbo]

Outer driveshaft joint if its knocking when cornering but not in a straight line, does it do it more when comming off roundabouts?

 

[Willie]

Wheels bearings are very very subtle on the Leons when there on there way out.
Sounds like loose wheel or CV joint to me

 

[mrwookie]

Agree with Willie sounds like CV joint as had these go a few times on previous cars. May be worth jacking the car up and seeing if the boot on the CV has split also.

 

[Garetht]

Thanks

Will jack the car up today to have a look.

If it is the CV boot is that something that can be done at home ?

If the boot has split you'll no doubt have lost the grease which fecks the cv joint. Replacing the boot won't help, you need to replace the damaged cv joint as well as the boot.

Yea fairly easy to do as long as you have some mechanical savvy.

Not for Seat's but gives you an idea of whats involved replacing the boot

and the joint itself.

Good news

Whilst looking at the car today i noticed that the 3 normal wheels nuts were loose!!!!!!

Gave them a tighten and all seems to be ok.

Any reason why they would start to come loose ?

Cheers for all the replies.
